The Swiss Digital Summit was created with the goal of informing the public of trends and new achievements in IT. Researchers from all over the world present their research in a language to be understood by the public in general, while keeping the scientific depth at the highest academic level. As we approach this year’s edition which will be held the 4th November 2021, we invite you to revive last year’s summit which main theme was Digital transformation in economy and society. Here is Part 3 of this video series : you will hear Prof Bertrand Meyer, from the Schaffhausen Institute of Technology (SIT) about “The PEGS Approach: a Standard plan for Requirements engineering”.
